Originally planned as a pack-in cassette title for Amiga's never released Power Module peripheral, and later as one of three 3-D games on the first Power Play Arcade cart. 3 different prototypes exist, each being a different level of the game. Unfortunately, none of the prototypes are 100% complete, but two are playable. The game uses the traditional red/blue anaglyph glasses.

Now somebody knows for sure...'
